Our take
Dell identifies the 2155cn as a networked color laser multifunction printer with print, copy, scan and fax. Its family specification sheet rates Letter output up to 24 ppm in simplex mode and documents a 35-sheet ADF, 250-sheet main tray plus a one-sheet multipurpose feed, Gigabit Ethernet and USB. Wireless is an optional dongle. The sheet covers the related 2155cn and 2155cdn configurations but does not establish which duplex hardware is fitted to every cn unit; that field stays unresolved here. This is a wired small-workgroup MFP, not a confirmed automatic-duplex recommendation.
A small office that needs color printing, copying, scanning and fax over a wired network and can verify the exact unit configuration..
Avoid it when built-in Wi-Fi, automatic duplex confirmed on the exact unit, a high-volume recommendation or current-model support is a must.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Dell documents color print, copy, scan and fax in the 2155cn family.
- The 35-sheet ADF and scan-to-email, network-folder, application and USB options support paper-to-digital work.
- Gigabit Ethernet and USB are standard, with an optional second 250-sheet drawer.
What to weigh up
- Built-in wireless is not standard; Dell lists an optional wireless adapter.
- The reviewed family sheet does not distinguish the cn model's duplex hardware well enough to claim automatic duplex.
- Dell's typical monthly duty-cycle wording is not a recommended monthly range for the matching profile.
The key details

|---|---|
| Main functions | Color laser print/copy/scan/fax |
| Print output | Up to 24 ppm Letter simplex; monthly recommendation not established |
| Two-sided printing | 35-sheet ADF; Gigabit Ethernet and USB; wireless optional |

What the features mean for you
One machine covers the color document loop
Dell describes the 2155cn as a color laser MFP that prints, copies, scans and faxes. Its scanner supports a flatbed and a 35-sheet automatic document feeder, with scan destinations including email, SMB or FTP, an application and USB memory. Those functions suit an office that receives paper and must route digital copies without adding a separate scanner. The reviewed sheet does not say that the ADF reverses for two-sided scanning, so this review treats duplex scanning as unknown. If two-sided originals are routine, verify the exact machine and workflow before choosing it.
Published speed is a ceiling for simplex jobs
Dell rates the 2155cn family up to 24 pages per minute on Letter in black and color for simplex printing. The same sheet gives a lower duplex speed for the family, but it does not establish the duplex hardware on the exact cn configuration; the 2155cdn is a separate named variant. The 24 ppm number is a manufacturer maximum, not a promise for every file, print setting or aged unit. The source also lists a typical monthly duty-cycle figure, not an exact-model recommended workload. For that reason the matching profile leaves monthly guidance unknown.
Keep the cn and cdn hardware distinct
The product sheet covers both 2155cn and 2155cdn. Those similar names do not prove interchangeable paper handling. The sheet's duplexer line refers to a different 2150cdn and does not explicitly settle the 2155cn's installed automatic duplexer, while the 2155cdn is also treated separately in the manufacturer material. This review therefore does not score automatic duplex as confirmed. Before buying a used 2155cn, inspect its product label, rear and internal paper path, and printer configuration page. If automatic two-sided printing is a hard requirement, use a model whose exact configuration is explicitly documented.
Wired sharing is the standard connection story
Dell lists a Gigabit Ethernet port and USB 2.0 as standard interfaces. A wireless port is supported with an optional adapter, so a listing title that says wireless does not establish that the accessory is present. The Ethernet option is the more straightforward fit for a shared office queue; USB is available for a local host. Dell's family sheet is old, so check driver support for the computers and network security policies the office uses now. No present-day wireless service, mobile app support or compatibility is inferred from the historical product sheet.
Paper handling suits a small shared office
The standard input is a 250-sheet tray and one-sheet multipurpose feed, with an optional additional 250-sheet drawer. The listed maximum is 501 sheets, and output capacity is 150 sheets. The ADF accepts a range of common office sizes up to Legal; the platen supports a smaller maximum. This combination can reduce hand feeding for ordinary letter-size work, while the multipurpose feed is better for less common media. Check whether the optional drawer is actually fitted, and do not confuse the published maximum with equipment included in an individual used listing.
Treat legacy condition and supplies as separate questions
Dell's sheet describes toner reporting and alerts, a toner conservation setting and recycling, but those controls do not reveal what remains in a used machine. Before relying on the 2155cn, inspect color alignment, print quality, scanner glass, ADF pickup, fax-line operation, Ethernet and USB. Confirm the exact model suffix and look up supplies and drivers for that unit. This article does not infer a current warranty, replacement unit, service entitlement, price or stock from Dell's historical service description. A more recent MFP may be easier to integrate if the office needs ongoing vendor support.
What else to compare
Choose a current MFP if driver support is a priority, or select an exact configuration with confirmed duplex hardware when two-sided output is essential.
Before you buy
Does the Dell 2155cn print in color?
Yes. Dell describes the 2155cn as a color laser multifunction printer with black and color output.
Can it copy, scan and fax?
Dell lists copy, scan and fax in addition to printing for the 2155cn family.
Is Wi-Fi included as standard?
No. Dell lists a wireless port for an optional dongle; Gigabit Ethernet and USB are standard.
Does every 2155cn have automatic duplex?
The reviewed Dell family sheet does not settle that exact configuration, so confirm the duplex hardware on the individual 2155cn.

The decision
The 2155cn is most compelling for wired color copy, scan and fax in a small workgroup. Wireless and exact duplex configuration require additional verification.
